近年來隨著經濟的蓬勃發展,人們的休閒需求隨之增加。許多人選擇到夜店來從事娛樂或釋放壓力。夜店通常都會兜售含酒精成分的飲料或者酒類。也因為這樣,許多人在這樣的環境下不勝酒力,醉倒在夜店或街上,造成社會觀感不佳;更讓有心人士有機可乘。但目前卻沒有有效的方式來預防此類型的狀況。 本研究透過模擬出發到夜店到離開夜店安全回家的情境,開發一整套的智慧型夜店安全APP,其中使用的工具包括三軸加速度判斷酒醉步伐、GPS環境偵測定位和室內音量大小偵測等。此APP能對使用者提供主被動的安全保護;讓使用者在狂歡之餘,還能有效的兼顧自身安全。關鍵字:智慧型偵測、夜店、安全 Taiwanese need more different types of entertainment after work as Taiwan’s economy growing rapidly these years. A lot of people choose to go to nightclubs looking for fun or releasing their pressure. Since nightclubs often selling alcoholic drinks or wine, many people drink beyond their capacities and drunk at nightclub or on the outside street. It not only makes a bad impression in the public but also gives villains chances to hurt people as them leaving the nightclubs. It seems there is no efficient way currently to prevent these crimes happening.In this study, we develop a smart nightclub safety-based application (APP) that simulate a scenario with a person leaving his house and go to a nightclub, stating in nightclub and backing his house. This APP used many mechanisms including a three-axis accelerometer, GPS positioning, volume detection and so on. It provides active and passive safety protection for users. The users can apply this APP to protect themselves as they on the way to nightclub or home and also can really enjoying in nightclubs without safety worry.Keywords: nightclub, smart, safety, application
